New subject: [math-fun] Metal cube puzzle
I recently put together a column on modern burr puzzles for maa.org. One thing I came across is http://www.maxton.com/max5.html -- which features elaborate dissections of a cube into interlocking pieces, and made with many different types of metal. Has anyone played with one of these? --Ed Pegg Jr
